axistetra: Plot reference axes in a static tetrahedral colorspace

Description

Plots reference x, y and z arrows showing the direction of the axes in a static tetrahedral colorspace plot.

Usage

axistetra(x = 0, y = 1.3, size = 0.1, arrowhead = 0.05,
  col = par("fg"), lty = par("lty"), lwd = par("lwd"),
  label = TRUE, adj.label = list(x = c(0.003, 0), y = c(0.003, 0.003),
  z = c(0, 0.003)), label.cex = 1, label.col = NULL)

Arguments

x, y

position of the legend relative to plot limits (usually a value between 0 and 1, but because of the perspective distortion, values greater than 1 are possible)

size

length of the arrows. Can be either a single value (applied for x, y and z) or a vector of 3 separate values for each axis.

arrowhead

size of the arrowhead.

col, lty, lwd

graphical parameters for the arrows.

label

logical, include x, y and z labels (defaults to TRUE).

adj.label

position adjustment for the labels. a list of 3 named objects for x, y and z arrows, each with 2 values for x and y adjustment.

label.cex, label.col

graphical parameters for the labels.

Value

axistetra adds reference arrows showing the direction of the 3-dimensional axes in a static tetrahedral colorspace plot.
